A patent showing a curved sensor equipped with DPAF has appeared, like the stacked sensor patents, curved sensors appear to be getting closer to being brought to a product. Canon News interprets Japan Patent Application 2018-014657: The sensor uses a piezoelectric device to drive the shape change of the curved sensor and has strain gauges (219) to Read more...

Curved sensor mania first took over the blogosphere back in 2014 thanks to Sony and their curved creation. But while that sensor never really came to anything worthwhile—although it was used in a “camera”—two Canon patents are sparking interest in this technology once again. petapixel.com »

A new patent suggests Canon’s engineers might be working on a curved sensor design to reduce vignetting. Japanese blog Egami reports on a patent that was released on the 24th of November and describes an image sensor design with a flat central portion, where light fall-off from the lens is not much of an issue, and curved edges, where fall-off is generally more noticeable. dpreview.com »

The thermal hurdles engineers must overcome become even more significant as cameras get increasingly more robust video recording features. A new Canon camera patent hopes to overcome these concerns through a relatively compact active cooling system to keep internal recording media cool. [Read More]
According to a new report, Apple is considering putting infrared cameras into future models of its popular AirPods wireless earbuds. [Read More]
Thanks to improvements in sensor design, iPhone and Android smartphones are gaining traction with enthusiast and professional creators. However, one area that has lagged behind developments in imaging sensors is image stabilization.
This patent application (Japan 2023-125903) has a lot of esoteric fast zoom lenses in some very nontraditional focal lengths. Many of the embodiments are missing the image height, however since we also have the half angle of view, we can work backward to verify if these lenses are meant for full frame or for APS-C.
Canon has filed a patent in Japan that shows what appears to be a compact built-in teleconverter that relies upon external controls and internal actuators to provide photographers with quick access to various focal lengths. [Read More]
In this Japan Patent Application, JP 2023-118490, Canon is investigating creating smaller built in teleconverters for use in lenses that we would normally not expect to see a teleconverter installed in.
It's been a few years since we first started reporting on the possibility of an affordable “box” style cinema camera from Canon. For a while we were running with the name Canon Cinema EOS C50.
